Congratulations upon your selection of this CASIO watch.

 Note that the product illustrations in this manual are intended for reference only, and so the actual product

may appear somewhat different than depicted by an illustration.

This watch does not have a city code that corresponds to the UTC offset of –3.5 hours. Because of this, the radio-controlled atomic timekeeping function will not display the correct time for Newfoundland, Canada.

 The measurement functions built into this watch are not intended for taking measurements that

require professional or industrial precision. Values produced by this watch should be considered as reasonable representations only.

 To ensure correct direction readings by this watch, be sure to perform bidirectional calibration before

using it. The watch may produce incorrect direction readings if you do not perform bidirectional calibration. For more information, see “To perform bidirectional calibration” (page E-37).

 Note that CASIO COMPUTER CO., LTD. assumes no responsibility for any damage or loss suffered

by you or any third party arising through the use of this product or its malfunction.

Charging the Watch

The face of the watch is a solar panel that generates power from light. The generated power charges a built-in rechargeable battery, which powers watch operations. The watch charges whenever it is exposed to light.

Charging Guide

Warning! Leaving the watch in bright light for charging can cause it to become quite hot. Take care when handling the watch to avoid burn injury. The watch can become particularly hot when exposed to the following conditions for long periods.

 On the dashboard of a car parked in direct sunlight  Too close to an incandescent lamp  Under direct sunlight

E-10

Whenever you are not wearing the watch, be sure to leave it in a location where it is exposed to light.

 Best charging performance

is achieved by exposing the watch to light that is as strong as possible.

When wearing the watch, makes sure that its face is not blocked from light by the sleeve of your clothing.

 The watch may enter a sleep

state (page E-14) if its face is blocked by your sleeve even only partially.

Important!

 Keep the watch in an area normally exposed to bright light when storing it for long periods. This helps

to ensure that power does not run down.

 Storing the watch for long periods in an area where there is no light or wearing it in such a way that it is

blocked from exposure to light can cause power to run down. Make sure that the watch is exposed to bright light whenever possible.

Checking the Current Power Level

You can use the procedure below to determine the watch’s current power level. Certain functions will be disabled when the power level is low. If the power level is low, leave the watch in a location where its face (solar panel) is exposed to light.

 When the watch is at Level 3, exposing it to light for a while will cause the x Second Hand to move to

the position of second 57. This indicates that charging has started.

Power Recovery Mode

The watch is designed to go into a power recovery mode that stops hand operation temporarily whenever power suddenly drops below a certain level due to continuous signal reception or other operations over a short period. Note that all operations are disabled while the watch is in the power recovery mode. The hands will move to the correct positions and the watch will resume normal operation after power recovers (in about 15 minutes). Putting the watch in a location where it is exposed to light will help power to recover sooner.

Radio Controlled Atomic Timekeeping

This watch receives a time calibration signal and updates its time setting accordingly. However, when using the watch outside of areas covered by time calibration signals, you will have to adjust the settings manually as required. See “Conﬁ guring Current Time and Day Settings Manually” (page E-28) for more information.

This section explains how the watch updates its time settings when the city code selected as the Home City is in Japan, North America, Europe, or China, and is one that supports time calibration signal reception.

If your Home City Code setting is this:

LON (LONDON), PAR (PARIS), ATH (ATHENS) Anthorn (England), Mainﬂ ingen (Germany)

HKG (HONG KONG) Shangqiu City (China)

TYO (TOKYO) Fukushima (Japan), Fukuoka/Saga (Japan)

HNL (HONOLULU), ANC (ANCHORAGE), LAX (LOS ANGELES), DEN (DENVER), CHI (CHICAGO), NYC (NEW YORK)

Important!

 The areas covered by HNL (HONOLULU) and ANC (ANCHORAGE) are quite far from the calibration

signal transmitters, so certain conditions may cause reception problems.

The watch can receive the signal from the transmitter located here:

 Auto Receive: Leave the watch over night in the location you selected in step 2. See “Auto Receive”

on page E-18 for details.

 Manual Receive: Perform the operation under “To perform manual receive” on page E-19.

Auto Receive

 With Auto Receive, the watch performs the receive operation each day automatically up to six times (up

to ﬁ ve times for the Chinese calibration signal) between the hours of midnight and 5 a.m. (according to the Timekeeping Mode time). When any receive operation is successful, none of the other receive operations for that day are performed.

 When a calibration time is reached, the watch will perform the receive operation only if it is in the

Timekeeping Mode. The receive operation is not performed if a calibration time is reached while you are conﬁ guring settings.

Radio-controlled Atomic Timekeeping Precautions

 Strong electrostatic charge can result in the wrong time setting.  Even if a receive operation is successful, certain conditions can cause the time setting to be off by up

to one second.

 The watch is designed to update its day setting automatically for the period from January 1, 2000

to December 31, 2099. Updating of the day setting by signal reception will no longer be performed starting from January 1, 2100.

 If you are in an area where signal reception is not possible, the watch keeps time with the precision

noted in “Speciﬁ cations” (page E-64).

 The receive operation is disabled under any of the following conditions.

− While power is at Level 2 or lower (page E-12)

− While the watch is in the power recovery mode (page E-13)

− While the watch is in the function sleep state (power saving, page E-14)

− While the watch is not in the Timekeeping Mode

− While a direction reading or Countdown Timer operation is in progress (even if the watch is in the

Timekeeping Mode)

 A receive operation is cancelled if an alarm sounds while it is being performed.
